WILLIAM J. STEWART AND GUY STEWART, OF NEW YORK, N. Y.

CAN AND ori-IER' VESSEL'.

Specification of Letters Patent.

` Patented Nov. 13, 190e.

To a'ZZ whom it may concern.-

Beit known that we, WiL-MAM J. STEWART and GUY A. STEWART, citizens of the United States, residing at New York, in the county of New York and State of New York, have mvented or discovered certain new and useful Improvements in Cans andother Vessels, ofl

which theollowing is a speciiication, reference being had therein to the accompanying drawings.

This invention has for its obj ect to provide a closure for a can, bottle, or similar vessel, and which will be of such construction that any desired amount of powdered' or granular material contained in such vessel may be positively fed ,therefrom in a convenient and reliable manner.

To this end the invention comprises a neck, which may be a permanent orti on of the can or which may be adapted or attachment to a bottle, jar, or similar vessel, the said neck being provided with a discharge-opening and having attached thereto and rotatably mounted thereon a cap which is provided with a feed-screw and which cap and screw may be turned by the thumb and finger ofthe user in such a manner as to dischar e any desired amount 'oi' material from tie vessel. Thesaid neck is also preferably provided with a sleeve attached in such a manner as to be partially rotatable,the said sleeve being provided with an opening-or hole which may be brought into register with the discharge-aperture in the neck of the can. when it is desired to feed a uantity of the material from the can and wiich sleeve may be partially rotated to close the discharge-aperture in the said neck. t

In the accompanying drawings, Figure 1 is a sectional elevation oia can embodying the present invention, ada ted to contain toothpowder or the like. ig. 2 is a plan view ot the top ofthe cap. Fig. 3 is asectional yiew of the ca having a feed-screw attached thereto. ig. 4 is a detail sectional view of the partially-rotatable sleeve. Fig. 5 is a detail sectional view of the neck on which the sleeve is to be mounted. Fig. 6 is a sectional view of the invention as adapted to be applied to a bottle, jar, or similar vessel. Fig. 7 shows a slightly-modified form of the invention.

Referring to the drawings, 12 denotes a can, which may be of tin or other suitable sheet metal and which is provided with a permanently-attached neck 13. Said neck is provided near its top with an` annular groove or depression 14, adapted to receive an indented or grooved portion 15 on a downwardly-extending ange 16 'of a cap 17, so that the said cap will be secured to the said neck in such a manner as to permit it to be easily turned or'rotated.

Permanently attached to the cap 17 by soldering or otherwise is a feed-screw 18, which extends down through the said neck, the latter being provided with a dischargea erture or feed-opening 19, through which t e material contained in the can may be discharged when the can is turned down horizontally simply by rotating the said cap, and

thus turning the feed-screw attached thereto. Such rotation ot the cap and feed-screw will positively force out through the dischargea erture or feed-opening any desired amount o powder or granular material which may be contained in the can, and as the said cap, which is preferably corrugated or roughened at its eriphery, may be readily turned by the thumb and finger of the user any desired amount of material can thus be ted from the said discharge-aperture. Such rotation of the cap and screw may easily be effected bv the thumb and finger of the same hand which holds the vessel, so that, for example, if the can contains toothowder, one hand of the user may hold the rush on which any desired quantity of the tooth-powder may be dropped from the can without shaking the latter1 the feed-discharge being positive, so that the amount of material fed. from the can may be readily gaged or determined. The neck 13 is also provided with a partial annular groove 20, which receives an indentation 21 on the sleeve 22, so as to permanently attach said sleeve to said neck in such a manner that the said sleeve may be partially rotated on said neck to bring the opening or hole 25 therein into register with t e aperture 19 in said neck when material is to be discharged or may be turned to close said aperture.

The form of the invention shown in Fig. 6 is adapted for use in connection with a widemouthed bottle or jar 23 and in which the neck 13 is inserted in a cork 24, which in turn is fixed in the mouth of the said jar or bottle. ticularly adapted for use in connection with drug ists' bottles or jars containing owdere or granular material and from which it is frequently desirable to discharge a predetermined amount of material wlthout dis- IOO IOS

chargin too much, as into a scale, when the materia is to be weighed,v or when `a certain' amount of a given material is to be used, as in compounding prescriptions or the like.

Instead of locking the rotatable capto the neck by forcing the material of the parts inward to forni inturned locking-grooves or flanges, as above described, this result may be effected by forcing the materials of these arts outward, as shown 1n Fig. 7, zand the interlockin parts of the neck and sleeve may also be simi arlyforrned, as shown in saidFig.

7. This construction may be preferable, as

it will permit .a more tightly-fitting screw to be inserted in theneck; but otherforms of joining the parts together may be= employed Without departing from the invention.

From the foregoing iL Will be apparent that the invention comprises means wherebya certainarnount'of powder on granular material may be discharged from a can or other vessel containing thesame ina-.positive and reliable-manner, such discharge being conseams y veniently effected by the hand which holds the vessel, which latter Will of course be turned over horizontally, or approximately so, when thematerial therein 1s to be dis- Havin thus described our invention, we claim-an desireto soc ure by Letters Patent- The combination With a neck provided with a disch aree-aperture, of a cap rotatably attached to said neck, and a feed-screw per-l manently attachedto said ca saidnec-k bein providedr with a partially-rotatable sleeve in ependent-iof said cap and havingean opening-Wnich'may be'brought into register with i the saidaperture in saideap. and which latter maybe closed by partially rotating said sleeve Initestimony Whereo'fwe affix our signatures in4 presence of two Witnesses. l
